I know there are a fair number of WLED Controller boards on the market, but for me it's more fun to create one than buy one. So here is my take on this...

If you are not familiar with WLED, it's awesome firmware that comes preinstalled on the AJAPixel, and then used either via it's internal Web page or IOS / Android app. It's used to control strings of "smart" LEDs more commonly known as NeoPixels. These are what are used in the awesome outside holiday displays you se all over the place.

I use this to control lights in my home theater and around my outside deck area.

AJAPixel is delivered without a housing or project box and will need to supply your own.

AJAPixel can run on any voltage between 5V and 20V and does provide a relay connection. I also added 4 of the digital IOs to holes for a pin header for any future expansion.
